BC: Different Birds and How Their Systems Work | Birds have to have good reflexes to survive. They need these good reactions for getting away from predators and even just landing. A bird has these quick reactions from its brain and their sensitive hearing and seeing. Their senses have adapted to this from years of looking and listening for prey and generations of surviving. Birds reproduce by internal fertilization. Though the eggs they lay are similar to reptile eggs, they have harder shells to help the egg stay in tact. One of the parents prepares a nest for the young; then one of the parents has to keep the egg at a certain temperature for it to develop. In some species, parents take turns incubating the egg and in others, one parent incubates the egg. The parents have to incubate the egg until it hatches. This can be anywhere from 12 days to 80 days. The time for it to hatch depends on the size of the bird. Once the egg hatches, parents watch over the chick at until they can fly. There are 10,000 species of birds, making them the most diverse land dwelling vertebrates. This is because they have many adaptations for the environments they live in. Birds also have to have adaptations to fly, reproduce and care for their young. Birds are important for many reasons from entertainment to food. They also liven up everyday life. Birds provide food, feathers, some pollinate plants, some carry the seeds from plants away and drop them someplace else to start new plants and many birds also get rid of pests. The orders of birds are bee-eaters, ostriches, long-legged waders, woodpeckers, birds of prey, owls, and perching birds. Bee-eaters eat insects and keep the insect population down. Ostriches can't fly, but they can run fast to get away from predators. Long-legged waders have long legs which let them stand in water and catch prey. Woodpeckers peck trees with their beaks to find insects and other little animals to eat. Owls come out at night and hunt rodents. Birds of prey scour the sky and look for prey on the ground. Perching birds have the ability to perch on a branch naturally because of their feet.

1: The Life of a Bird | A bird is an endothermic vertebrate that has feathers,a four-chambered heart, and lays eggs. They have 2 kinds of feathers. They have contour feathers and down feathers. Contour feathers give shape to the body and help it in flight. Down feathers keep a bird warm by trapping warm air on the bird's skin.Birds are toothless. All species have different bills for their different feeding habits. Birds use their digested food for energy, as they need energy to keep their body temperature constant. Birds have a system of air sacs connected to their lungs in their bodies. They allow the bird to get more oxygen from each breath.

2: There is an invisible ocean of air around all objects.Air is a mixture of gas molecules that exert pressure on the objects they surround. Moving air exerts less pressure than air that is not moving.The lower surface of a wing is flatter than the upper surface. The difference between the lower and upper wing enables flying creatures to fly.Faster air exerts less pressure than slow moving air. The air above the wing is has less pressure than the air under the wing. This difference in pressure causes the upward force known as lift. | Birds are some of the most magnificent creatures on Earth. Their unique structure is different from all other animals with different types of wings for their different specialization of flight. But the design of of their wings isn't the only component that enables the bird to fly. The bird must have some way of getting of the ground. The bird must move forward, since lift depends one air moving over its wings. When the pushes itself off the ground, its sharply pulls its wings down. This downstroke provides the needed lift needed for flying. | The Physics of Bird Flight

4: The Biomes that Birds Live in | The class Aves (birds), live in a variety of biomes. Each bird that lives in a different biome has adaptations that help it survive more. Birds live in tropical rainforests, savannah, temperate rain forests, desert, deciduous forest biomes, taiga and tundra. Some birds also live in freshwater biomes and estuaries. Ducks and seagulls live in the water biomes. Ostriches live in some savannahs, a parrot is one type of bird that lives in a tropical rainforest, woodpeckers live in deciduous forest and taiga, and arctic loons live in the tundra.

5: The Reproduction of Birds | Birds are internally fertilized and lay eggs. Their eggs are like reptile eggs, other than the fact that they are harder. Birds will only develop near their parent's body. The eggs are incubated near the parent's body and are usually taken care of by only one parent. Birds take different amounts of time to hatch. A chick pecks its way out of the egg. Some newborns are very weak and feeble, while others can even run around straight out of the egg. The babies are usually fed by the parents until they can fly.

6: The Food Menu of Birds | Birds eat many different kinds of organisms from berries to fish. Many birds eat insects, but some birds even eat small vertebrates like rabbits and fish. Birds also eat the fruit of plants. Most of these seeds go right through their digestive system and start new plants.

7: Behaviors of Birds | Bee-eaters- Before they eat the prey, they sting the prey and drain their venom. Ostriches- The ostrich is one of the fastest animals in the world. Long-legged waders- Wait for their prey to come by being still. Woodpeckers- The woodpecker can bang trees with its beak to look for insects. Birds of prey- Stalk the sky until they see prey. Owls- An owl's head can turn up to 270 degrees in one direction. Perching birds- Their feet automatically lock onto branches.

8: The Symmetry of Birds | Birds are bilaterally symmetrical, which means that if cut them in half, the halves will be mirror images of each other.

9: The Era/Period of the Birds | The first birds appeared during the Jurassic Period of the Mesozoic Era. The name of the first bird is Archaeopteryx.

10: The food Web | The sun burns furiously as the mighty eagle glides down from the sky to grab its lunch, a python. Birds are one of the biggest predators in the food web. Although they may become prey, they are still one of the topmost predators. What is the first thing that comes to your mind when you talk about flying animals? Yup, it is birds. These creatures have wings which allow them to evade most predators and capture most prey their size.

11: The Genus Amazonetta | What makes this genus so great is that the Brazilian Teal(Amazonetta brasiliensis) is the bird animal in this specific genus. One of the main thing that catches your eye when you see this bird is its magnificent and vibrant colored wing. Their preferred habitat is a body of freshwater away from the coast with dense vegetation nearby.
